IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 49,955, dated September12, 1865.

To all whom it may concern:

Be it known that l, JAMES S'rRA'rToN, of Philadelphia, Pennsylvania,have invented an Improved Vapor-Burner; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

Myinvention relates to improvements in that class of vapor-burners whichare used for both heating and culinary purposes; and my improvementsconsist,iirst,in conducting the uid from which the gas has to begenerated through, annular, or nearly annular, tube which communicateswith and is arranged above a nipple, substantially as describedhereinafter, so that an intense heat may be imparted to the said annulartubes and the fluid there rapidly convertedinto gas 5 second, of a plateadapted to the said annular tube in the manner described hereinafter, sothat the said plate can be removed and culinary and other vessels placedon the tube and subjected to the direct action of the lia-me, third, inthe combination ot' a nipple of peculiar construction with a valverodhaving a needle-point for penetrating the orifice of the nipple 5fourth, in an extinguishing-cap adapted to the nipple and having apointed rod for penetrating the orifice of the same, all as describedhereinafter.

In order to enable others skilled in the art to make and use myinvention,I willnow proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of thisspecification, Figure l is a sectional elevation of my improvedvapor-burner for stoves, Svc., Fig. 2, an elevation, partly insection,looking in the direction of the arrow, Fig. 1; Fig. 3, a planview; Fig. 4, a detached sectional view of part of the burner, drawn toan enlarged scale; and Fig. 5, an illustrative diagram.

Similar letters referto similar parts throughout the several views.

A is a tube, a portion, a, of which may be straight, a portion, a',being bent in the form of arin g, while the remainingportion,a",projects downward from the end a: of the ring, and communicatesthrough a horizontal pipe, C, with a chamber, D, to the top of which issecured a nipple, E, the latter being directly below, or

nearly below, the center of the ring formed by the portion o of the tubeA.

In the upper end of the nipple E is an opening, c, and below the latteris a conical valveseat, to which is adapted the upper conical end of ascrewed rod, F, which passes through and screws into the bottom of thechamber D.

To the lower end of the rod F is secured a hand-wheel, Gr, or itsequivalent, and from the upper end of the rod projects a needlepoint,e,for a purpose described hereinafter.

H is a metallic disk or plate, which is suspended within the ring a bylugs or arms ff, which project from the said disk and rest on the saidring.

The annular portion of the tube A is first heated in any suitablemanner, and naphtha, coal-oil, or other suitable fluid is introducedinto the tube, along which it ows toward the chamber D and through thenipple E, where the gas generated by the decomposition ofthe material inthe heated portion ofthe tube is ignited, the rod F being withdrawn topermit the escape of the gas in such quantity as may be desired. As theame trom the burning vapor impinges against the plate H, it is deflectedin all directions toward the annular portion a' of the tube, which in ashort time is heated to redness, and is maintainedin this condition, sothat the gas is generated continuously and in such quantities as to beimpelled violently against the under side of the p'late H, heating thelatter, the tubular rin g a', and the air which surrounds the same. j

When it is desirable to diminish the ame the rod F is raised so as topartially obstruct the opening c in the nipple. When, however, itbecomes necessary to extinguish the ame altogether, a metal cap, I,isplaced over the nipple, a pointed rod, i, in the interior of the capprojecting into the opening c and preventing the clogging of the latter.After the burner has become perfectly cool the cap Iis removed and therod F is raised until the conical end of the same is brought firmlyagainst its seat. Gare should be taken not to close the valves until theperfect cooling of the tube is effected, as the expansion or continuedformation of the gases in the same, without the means of escape, wouldcause the pipe to burst, or at least occasion leakage at the joints.

Where it is desirable to heat any substance contained in a vessel theplate H may be removed and the vessel be placed directly on the tube A,the bottom ofthe vessel acting in place of the plate to deflect the ameagainst the tube.

In burners of this character heretofore used a plate similar to theplate H has been permanently connected by arms to a heater or reservoirsurrounding the nipple, the heat from the plate being conducted by thearms to the reservoir, so that the fluid on reaching the latter wasdecomposed. This arrangement, however, was objectionable, as thereservoiris never heated to redness and the decomposition ot' the gasesis not affected so thoroughly and rapidlyasdesired. Inthesedevices,also,theopen ing in the nipple is ofthe character shown inFig. 5, so that it is constantly enlarged as the valve-seat Wears away.

By the arrangement above described the tube A isheated to such a highdegreethat the tluid is thoroughly decomposed before it reaches thenipple, and coal-oil and other similar substances unsuitable for use inthe ordinary burners of this class can be employed to as good advantageas the more expensive materials heretofore used.

Another important feature of my invention is thedetachability oftheplate H from the ring a', so that the direct action ot' the fire may beexerted upon any culinary or other article placed upon the ring a.

The importance ofthe point e on the rod F and the pin i on the cap I asmeans of closing the orifice ofthe nipple will be readily understood.

I claim as my invention and desire to secure by Letters Patentl.Conducting the Huid from which the gas is to be generated through anannular, or nearly annular, tube, which communicates with and isarranged above a nipple, substantially as and for the purpose describedabove.

2. The detachable deecting-plate H, adapted to the annular portion a ot'the tube A, substantially as and for the purpose described.

3. rI he nipple E, with its opening-c and its valve-seat, in combinationwith the valve-rod F and its needle-point e, the whole being constructedand arranged substantially as and for the purpose set forth.

4. The cap I, With its pointed rod adapted to the nipple E,substantially as and for the purpose specified.

In testimony whereofI have signed my name to this specification in thepresence ot' two subscriblng witnesses.
